Abstract
The synthesis and physical-chemical properties of anisotropic derivatives of (–)-L-lactic acid and its nanocomposites are discussed. We have used modification products, corresponding to 3,6-disubstituted cyclohex-2-enones, (–)ethyl-L lactate and optically active ethyl-ω-halogen alkyl lactates to synthesize anisotropic 2-aryl-oxypropionic acids, acrylic esters of 2-(4-brombutoxy)- and 2-(6-bromhexyloxy)propionic acids. The last ones are used for preparation of mesomorphic nanocomposite materials and their properties are studied. Anisotropic materials based on derivatives of lactic acid are capable of interaction with inorganic nanoparticles and potentially productive for new nanocomposite materials.
Keywords: optically active liquid crystals; nanocomposites, physical-chemical and optical properties of anisotropic nanocomposites
